IUI is defined as direct placement of the processed sperm into the uterine cavity at any point above the internal os.
Intrauterine insemination is also called artificial insemination, or IUI. Human artificial insemination with the male partner's sperm for infertility began being used in the 1940's.
IUI is usually suggested for those couples who have been trying to conceive for a year or more without success and have been found to have infertility issues. It is always recommended to perform a complete infertility examination before undergoing this process.
In the process of iui, the fertilisation of the egg and sperm occurs naturally, although the sperm is given a kind of "push" into the uterus. For this reason, both partners must meet certain criteria in order to have the best chances at success with IUI.
